Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ALEXANDER D. GRANT, a citizen of the United States,residing at San Jose, in the county of Santa Claraand State ofCalifornia, have invented new and useful Improvements in- SanitaryToilet- Bowls, of which the following is a specification. v

This invention relates to a sanitary toilet bowl. 1

The object of the present invention is to provide a receptacle in orexterior of a toilet bowl adapted to receive a disinfectant and toprovide means for automatically dis charging a quantity of same when thebowl is flushed.

The invention. consists of the parts and the construction andcombination of parts as hereinafter more fully described and claimedhaving reference to the accompanying drawings, in which Figure 1 is acentral, vertical section of the toilet bowl. Fig. 2 is a plan view online 22, Fig. 1.

Referring to the drawings in detail, A indicates in general the toiletbowl, 2 an intake opening which is connected with a tank or other sourceof water supply, not here shown; and 3 a discharge opening which isconnected with a main chamber 4 by means of a passage, indicated at 5.Formed in the intake opening 2 just above the openingv 6 leading intothe main chamber, is a pocket-or receptacle 7, which'is perforatedaround the sides and the bottom,

as indicated at 8 and 9; and formed just above said pocket, is anopening 10, which is adapted to be closed by means of a removable cover11. The pocket 7 is adapted toreceive or form a container for a disin--fectant, said disinfectant preferably being in the form of a solid,which is slowly dissolved by the action of the water.

Formed in the intake opening 2 just below the disinfectant receivingchamber 7 is a barrier 12 and similarly formed near opening 6, is abarrier 13; and extending from a point just rearwardly of barrier 13 tothe lower portion of the bowl, indicated at 14, is an auxiliary drainpassage 15, the function of which will later be described. The

removable cover 11 provided in this instance consists of the cover 11,on the lower end of which is formed a threaded extension 16, whichscrews into across-bar 17;

. curingthe cover in position.

this cross-bar is sufficiently long to extend across the opening and islowered into its normal position through slots 18, formed in the side ofopening 10. The cover 11 and bar 17 is then slightly turned until thebar assumes the position approximately such as shown in Fig. 2, out ofalinement with slots 18. The 'cover section is then turned by means of.a spanner wrench inserted into depressions 19 formed in the cover, thusPatented Apr. 11, 1916.

drawing the crossbar up against the under side of the opening 10; andthoroughly se- In operation it will be seen that flushing of the toiletwill cause the water from the source of supply to enter opening 2 in thedirection of arrow a. A portion of the water is here deflected upwardly,as indicated by arrowb, and is in this manner forced through openings 8into the chamber 7 containing the solid, but soluble disinfectant. Thewater then passes through opening 6 in the direction of the arrow,through the main chamber 4; passage 5, and finally through the dischargeopening 3; in the usual manner; flushed and the contents of chamber?become so saturated with water that a quantity of same is dissolved. Thedissolving matter'will then drain through the bottom perforations9andcollect between barriers 12 and 13,'where it is finally permitted todrain The toilet bowl is in this manner through passage 15 into thelower portion of the bowl, thus thoroughly disinfecting the bowl and thewatercontained' therein.

In practice it has been found that certain varieties of disinfectantshave a tendency to'stain the bowl. present instance, as none of thedisinfectis admitted through the main opening 6 and the bowl. Theauxiliary drain passage 15 being provided for the purpose of Thisis'obviated in the admitting the disinfectant tothe lower por- I tion ofthe bowl, where it is furthermore 16 1 most efiiciently applied.

The materials and finish together with the construction and the locationof the device, may otherwise be such as the judgment and experience ofthe manufacturer may dictate.

I wish it understood that various changes in form, proportions and minordetails of construction may scope of the appended claims, and that I donot wish to limit myself to thespecific design and construction hereshown.

be resorted to within the V sage formed in the bowl and leading fromsaid chamber to the bottom of the bowl.

2. The combination with the water inlet opening of a toilet bowl, of aperforated container formed insaid inlet opening, said container adaptedto serve receptacle for a disinfectant which is in a solid, but solublestate, and a barrier member mounted in the inlet opening below thedisinfectant container to. direct a portion of h flushing water throughthe container when the toilet is flushe 3. The combination with thewater inlet opening of a toilet bowl, of a perforated container formedinsaid inlet opening, said contalner adapted to serve as'a receptaclefor a disinfectant which is in a solid, but soluble state, a barriermember mounted in the inlet opening below the disinfectant container, .asecond barrier member mounted forward of the first-named barrier memberto form a pocket below the disinfectant con- .tainer, and a drainpassage formed in the bowl connecting Said Pocket, with the lowerportion of the-main chamber in-the bowl.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 'wltnessess ALEXANDER D. GRANT.
